In classical multilevel access control, classifications and clearance level are defined in
advance and does not change during the duration of their use. We thought that the level of …

The proposed multilevel access control model is based on description logic augmented with
default and exception to capture the context feature. In this model, the level is assigning to …

This paper present a dynamic multilevel access control model based on description logic
with default and exception to capture the context feature. To define a security policy …

The proposed access control model is based on description logic (DL) augmented with a
default (δ) and an exception (ϵ) operators to capture context feature. Our model is inspired …

Access control provides the mean of restricting the access to a computer system by checking
whether a legitimate user has the rights to perform certain actions on the resources …

It is a big challenge to establish a dynamic access control model to secure applications in
open and dynamic environment. The dynamic feature of an access control system is …

Role-Based Access Control (RBAC) has been recognized as a strategy which reduces the
cost and complexity of security administration in large-scale networked applications. A …

Access control policy is utilized to ensure that the available resources aren't accessed
unintentionally. Traditional access control policy approaches generally describe the core …

Relation Based Access Control (RelBAC) is an access control model that places
permissions as first class concepts. Under this model, we discuss in this paper how to …

The final objective of an access control model is to provide a framework to decide if an
action performed by subjects on objects is permitted or not. It is not convenient to directly …
